Description
[0001] This application is a continuation of U.S. patent
application Ser. No. 081/835,158, filed Apr. 4, 1997.
BACKGROUND OF THE INVENTION
[0002] The invention is generally concerned with a replaceable
mirror for motor vehicles and is more particularly concerned with a
replaceable mirror having a slidable mirror carrier plate.
[0003] A rear view mirror arrangement of this type is known from EP
0 609 508 A1. In the case of this rear view mirror arrangement, a
sliding connection between a holding plate for a removable
installation of a rear view mirror in a housing and the mirror
carrying plates is carried out by a clamp lock device. The latter
can function in practice in that the holding plate is provided with
projections in the area of two, oppositely disposed, parallel side
edges which, during clamping, can be pushed parallel to the plane
of the plate into complementary shaped depressions on the back of
the mirror carrier plate.
[0004] This previously known sliding arrangement is characterized
by a stable mounting and good withdrawal of the mirror carrier
plate away from the holding plate. However, this design is complex
in its molding technology, since connection projections are to be
provided on the holding plate as well as the complementary shaped
rear depressions on the mirror carrying plate. Moreover, in the
sliding of the mirror carrier plate onto the holding plate, though
seemingly simple of itself, in practice the projections on the
holding plate must be intuitively maneuvered into the complementary
shaped depressions of the rear area of the mirror carrier
plate.
OBJECTS AND SUMMARY OF THE INVENTION
[0005] Basing consideration on the problems recited above, it is an
object of the invention to improve the sliding connection between
the holding plate and the mirror carrying plate, so that the
manufacture and the manipulation work for the mirror arrangement is
reduced.
[0006] This purpose will be achieved by means of the present
invention. In accord with the invention, on the one hand there may
be provided at least one open insert channel, groove-like in shape
and aligned along the holding plate plane, into which a
complementary anchoring piece on the mirror carrier plate can
slide, parallel to the plane of the holding plate, during
replacement closure. On the other hand, a mirror carrier plate may
be provided as a slide-in connection possessing a trapezoidal
periphery. This has inwardly-turned clips correspondingly
trapezoidally arranged, parallel to the plane of the holding plate.
These clips, during a motion of sliding in along the plane of the
holding plate, embrace receiving clips curved outwardly on the rim
of the holding plate which has a periphery complementary to the
above.
[0007] To achieve a solid connection between the holding plate and
the mirror carrier plate, both of the above outlined preferred
methods of slide connection for the rear view mirror arrangements
can be realized, however, only one of the two methods of sliding
together at a time is possible. In addition it must be mentioned,
that the functional assignment of the individual designs of the
slide-connection in accord with the invention as to holding plate
or mirror carrier plate, can be reversed.
[0008] In the case of the two provided sliding connection methods
in accord with the invention, either is of advantage, in that in
spite of a very short slide movement, a stable and in the case of
commercial vehicles, an enduring fastening of the mirror carrier
plate, and thereby the mirror glass, on the holding plate is
achieved. This is more supported by the trapezoidal "wedge" action
of the securement fittings, which calls forth a precise securement
positioning of the mirror carrier plate on the holding plate at the
full stop point of the sliding final position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] Reference will now be made in detail to the presently
preferred embodiments of the invention, one or more examples of
which are illustrated in the drawings. Each example is provided by
way of explanation of the invention, and not meant as a limitation
of the invention. For example, features illustrated or described as
part of one embodiment of the invention can be used on another
embodiment to yield yet another embodiment. It is intended that the
present invention include such modifications and variations.
[0022] The external mirror presented in FIGS. 1, 2 for a commercial
motor vehicle is constructed as a double mirror. It possesses a
holder in the form of a double armed support 1 for the fastening of
the mirror on a schematically indicated body part 2 of a commercial
vehicle. The double support arm 1 is affixed to the vehicle body by
a bracket 3 which is swingable about vertical axis 4.
[0023] In an aerodynamic shaped mirror housing 5 a back plate 6 is
arranged which is fastened by means of an attachment means 7 on the
two holding pins 8,9 on the free end of the double arm support 1.
The housing 5 is supported directly on this back plate 6. At
appropriate points the back plate 6 can show designed cutouts,
which are not further detailed, to reduce weight.
[0024] Two mirror panes, 10, 11 are each swivelably secured to the
back plate 6 by movable supporting hemispheres 12, 13 respectively.
The lower mirror pane exhibits only a lightly convex main mirror
pane, the upper mirror pane 11 is a smaller wide angle mirror.
[0025] The lower mirror 10 is served by two adjustment means, 14,15
in the form of electrical motor-drive sets which are coupled to the
mirror 10 by means of a stepless crank drive 14, 15 which will not
be further described. By means of the adjustment aggregates 14, 15,
the mirror 10 can be adjusted through two adjustment axes 17,
18.
[0026] The holding apparatus 7 is designed as a clamping mechanism,
the clamp abutment 19 thereof being integral with the back plate 6
and serving also for the holding pins 8,9. The abutment 19 is
installed on the free end of a square projection 21 extending out
of plane 20 of the back plate 6. By means of a fastening screw (not
shown) a clamping jaw is lockingly bindable to the clamp abutment
19, whereby the back plate 6 is firmly affixed with the holding
pins 8, 9 of the support arms 1 when the clamping closure of the
clamping device takes place. Further detail on this point is
obtainable in the introduction in EP-609 508 A1.
[0027] In the assembly drawing shown in FIG. 2, the projection 21
penetrates through a not shown housing opening, which is found in
angular base 28 of a housing recess 30 on the outer housing side
29. The clamp abutment 19 and the clamping jaw of the clamping
apparatus 7 are also on the outside of the housing 29 and installed
in this housing recess 30, thereby being easily accessible for a
mounting of both mirror and support arm 1.
[0028] For the installation of the two swivelable support
hemispheres 12, 13, the description will be that of the under
support hemisphere 12 for the lower mirror 10. The upper swivelable
support hemisphere is correspondingly the same.
[0029] The swivelable bearing 12 is designed as a spherical ball
joint installed on the back plate 6, wherein the bearing shell 32
of the ball joint is integral with the back plate 6. The bearing
shell 32 is then installed at the free end of a ring-shaped
projection 33 protruding from the plate plane 20 of the mirror back
plate 6. Centrally, the bearing shell 32 exhibits as an integral
part a horizontally projecting, threaded sheath 34 in which a
fastening screw 35 is threadedly engaged for a not further shown
abutment flap which surmounts the threaded sheath 34. A compression
spring is supported therefrom which acts upon a spherical segment
shaped forcing element 38 in the direction of the bearing shell 32
of the swivelling support 12.
[0030] Between the pressing element 38 and the bearing shell 32
runs a hemispherical counter shell 39 for the mirror 10, and which
is molded on a flat holding plate 40. This counter shell 39 shows a
central opening 41, through which the threaded sheath 34 moves when
in use. On the holding plate 40 a mirror carrier plate 42 is
releasably fastened, to which the mirror 10 is permanently affixed
by adhesive.
[0031] As becomes further plain from FIGS. 1, 2, the housing 5 is
two pieced, comprised of a main piece 43 and a framing 44 which
conforms to the surrounding sides of the mirrors 10,11. The framing
44 exhibits in this function an outer lying peripheral area 45 as
well as the peripheries of the mirrors 10, 11, and said framing 44
is further provided with offset, flanking, inner lying wall
sections 46. Of these, there protrudes in the direction of the back
plate 6, integral, molded bracing members 47, which, between the
ends thereof, respectively a holding tab 48 is found running
parallel to the back plate 6. With these retaining tabs 48 the
framing 44 is integrally affixed to the molded fastening means of
the back plate 6.
[0032] The releasable fastening of each mirror carrier plate 42 to
the extended holding plate 40 which is integral with the counter
bearing shell hemisphere 39 of the swivelable mirror support 12,
13, is described for additional embodiments in more detail with the
help of drawings FIG. 3 to FIG. 11.
[0033] FIGS. 3, 4 show a first basic type of the releasable sliding
connection between the holding plate 40 and the mirror carrier
plate 42 of the present fastening.
[0034] The holding plate 40, in plan view is designed trapezoidal
with a bottom base side 49, a top side 50 parallel thereto and two
sides 51 and 52. Centrally located, as shown in FIG. 3 and FIG. 4
once again is apparent the counter bearing shell 39 with the
opening 41 for the swivelling support 12. The sides 49 to 52 of the
holding plate 40 are complementary to a designed general marking of
53 for a wedge shaped peripheral area on the mirror carrier plate
42. This peripheral area 53 is bordered by three support pieces,
54, 55, and 56, which, as is plain on FIG. 3, are continuous around
the two sides plus the short top base to realize a partial
trapizoidal collar 57. The wedge-type design of the peripheral
area, that is, the support pieces 54 and 55 arises from the slanted
arrangement of the two support pieces 54, 55, which form the
indicated wedge angle k. From the inside 58 of the two side support
pieces 54, 55 there projects respectively at about half the height
and toward the inside, fastening projection clips with a spatial
interval of "d" running in a plane P2. The gripping projection
clips 59 lie at a distance from the actual mirror carrier plate
which represents about half the thickness of the holding plate
40.
[0035] For assembly of the mirror carrier plate 42, with the mirror
10 on the holding plate 40, the mirror carrier plate 42, in accord
with the assembly end positioning as seen in FIGS. 3 and 4, is set
above on the holding plate 40 and subsequently pushed in the
direction indicated by the slip direction "S". After being so
slipped together, the sides 51, 52 and the upper base short side 50
of the holding plate 40 lie on the corresponding side positions 54,
55, and 56 of the mirror carrier plate, whereby simultaneously the
clip projections 59 grip the named sides 51, 52 of the holding
plate.
[0036] The embodiment shown in FIG. 5 differs from that in accord
with FIGS. 3 and 4, principally in that the straight sides 51, 52
of the holding plate 40 are curved outwardly. In complementary
manner thereto, the side support pieces 54, 55 have also a
correspondingly curved outline. The holding projections 59 are not
only available on the sides 54, 55, but also on the base side 56.
The interval offsetting them "d" is greatly reduced as compared to
the previous embodiment.
[0037] The assembly method for the embodiment in accord with FIG.
5, is little changed from that of the embodiment shown in FIGS. 3
and 4.
[0038] With the aid of FIGS. 6 and 7, the second fundamental slip
connection design in accord with the invention which is to be
described. Basically, in this case the matter proceeds from a
groove shaped reception channel 60 in the holding plate 40, which
is formed by a sprayed on, angular projection tab 37 which is
integral with the holding plate 40. Each receiving channel 60 is in
the direction of the plate plane P1, open toward the top and serves
for the reception of a complementary anchoring piece 62, which is
oriented downward in the opposite direction from the open side of
the reception channel 60 and is formed by an angular projection on
the mirror carrier plate.
[0039] As is made plain by FIGS. 6 and 7, there are, in the case of
the embodiment there shown, six groove characterized reception
pieces 60 about the counter bearing shell 39 and along the right
angled arranged sides 63, 64, 65, 66 of the holding plate 40 on the
rear side of the holding plate 40 facing away from the mirror
carrier plate 42. Two of the receiving channels lie in the area of
the upper side 63, two in the area of the lower side 64 and two at
half the distance between the counter bearing shell 39 and the
vertical sides 65, 66. So that the four last named reception
channels 60 are accessible for the respective complementary angular
projections 61 of the mirror carrier plate 42, in front of the open
side of these reception grooves is often a penetration 67 is made
in the holding plate 40 through which the respective angular
projection lockingly protrudes.
[0040] For the assembly of the mirror carrier plate 42 onto the
holding plate 40, the angular projections 61 of the mirror carrier
plate 42 with their anchoring pieces 62 are brought in front of the
receiving channels 60 and the mirror carrier plate is pushed in the
direction "S". Thereby, the anchoring pieces 62 lockingly engage in
the respective receiving channels 60 and there, preferably in
place, are releasably fastened.
[0041] The embodiment of the manner of connection between holding
plate 40 and the mirror carrier plate 42 shown in FIGS. 8 and 9
presents practically a combination of the designs indicated in
FIGS. 3 and 4 and FIGS. 6 and 7.
[0042] Once again a trapezoidal holding plate 40 is provided which
works in conjunction with a corresponding, wedge-like periphery 53,
formed from trapezoidal support collar 57 on the mirror carrier
plate 42. Further on the lower end of the holding plate 40, two
receiving channels 60 analogous to two lower receiving channels 60
on the square holding plate 40 as in FIG. 6 are provided, in which
once again the corresponding anchoring pieces 62 of the mirror
carrier plate fit.
[0043] As to the remainder, for coinciding construction pieces the
identical reference numbers have been used, so that a further
detailed description of the embodiments shown in FIG. 8 and FIG. 9
would be redundant. These are evident without any additional
comments from the description of FIGS. 3, 4, 6, and 7.
[0044] Finally in FIG. 10 is a further alternative for the basic
fastening construction as presented in the FIGS. 6 and 7. In this
case a right angled holding plate 40 is provided, on the lower side
of which a receiving channel 60' extends over the entire width. The
latter is again formed from a sprayed-on angular projection 37' and
lies, contrary to the previously described embodiments, on the side
of the holding plate 40 facing the mirror carrier plate 42. On the
mirror carrier plate 42, again an angular projection 61' is molded
on, which extends to the receiving channel 60' a complementary
anchorage piece 62'.
[0045] Over the top side 63 of the holding plate 40, which side is
oppositely disposed to the receiving channel 60', is a
complementary, molding like counter piece 68 which is slidable over
the holding plate 40 and which was formed from a corresponding
angular offset 69. The mirror carrier plate 42 is further provided
with a rib 69' upon which the upper rim area of side 63 is
supported, as shown in the assembly drawing, FIG. 11.
[0046] For the placement of the mirror carrier plate 42, this is
again placed on the holding plate 40 aligned in the sliding
direction S at the measured width of the anchoring piece 62' below
and, of course, the corresponding width of the counter piece 68
above and then pushed in said sliding direction S downward. When
this is done, the anchoring piece 62' enters the corresponding
receiving channel 60' in a tight fit. At the same time, the counter
piece 68 moves to engage behind the upper side area 63 of the
holding plate 40 whereby a stable connection between the two plates
40, 42 is created.
[0047] The relative displacement between the holding plate 40 and
the mirror carrier plate 42 is, in general, greater than the
remaining offset opening 73 between the outer edge 71 of the mirror
carrier plate 42 and the housing opening 72 which latter follows
the peripheral zone 46 about the mirrors (FIGS. 1 and 2). On this
account, in a normal rear view positioning of the mirror, as it is
shown in FIG. 2 for the lower main mirror 10, the mirror carrier
plate 42 is so encompassed by the housing 5 that a complete release
of the sliding contact between the mirror carrier plate 42 and the
holding plate 40 is impossible. Before the sliding contact between
said plates 40, 42 is released, the mirror carrier plate 42
impinges on the corresponding wall section 46 of the housing.
[0048] Only if the component group of the mirror carrier plate 42
and the holding plate 40 with the aid of the swiveling supports 12,
13, is tilted in an extremely pitched assembly position, as is
indicated by the position of the auxiliary mirror 11 in FIG. 2, can
the mirror carrier plate 42 be completely pushed out of the final
mounted position as shown in the dotted lines of FIG. 3 and lifted
from the holding plate 40. The extraction of the mirror carrier
plate 42 and its replacement is thus only possible in such an
extremely tilted position.
[0049] It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention
without departing from the scope and spirit of the invention. It is
intended that the present invention include such modifications and
variations as come within the scope of the appended claims and
their equivalents.
